Electromagnetic waves and circular dichroism- an animated tutorial
Electromagnetic waves are periodic changes of electric and magnetic fields in
space and time. They propagate at the speed of light. At any point of a light
beam, the magnetic field is always perpendicular to the electric field,

Waveguides waveguides are the most efficient way to transfer electromagnetic
energy. Waveguides are essentially coaxial lines without center conductors. They
are constructed from conductive material and may be rectangular, circular, or
elliptical in shape. A waveguide is forming by adding quarter-wave sections
shorted at one end on each side of a two-wire line. The lines become part of the
walls of the waveguide, as illustrated in the following figure. The energy is
then conducted within the hollow waveguide instead of along the two-wire
transmission line |

PROPAGATION OF RADIO WAVES |
|
Propagation of waves propagation, radio is all about the transmission of radio waves
from place-to-place without wires. Signals travel from the transmitting antenna
to the receiving antenna in different ways depending on the frequency used. Some
frequencies use the ionosphere to bounce signals around the world while other
frequencies can only be used for line-of-sight operations |
